Description

Technical Field

[0001] The invention relates to the field of medical appliances, and in particular to a portable mobile device with negative pressure drainage which is beneficial to postoperative rehabilitation. Background Art

[0002] As a treatment method, closed chest drainage is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy. Closed chest drainage combined with negative pressure suction helps to re-establish negative pressure in the pleural cavity, promote lung re-expansion, balance the intrathoracic pressure on both sides, reduce or eliminate residual pleural cavity, and plays a very important role in the treatment of the disease.

[0003] All of the above treatments require continuous negative pressure suction as a prerequisite. Accelerated recovery after surgery is a perioperative nursing measure that includes multiple disciplines. Early postoperative ambulation is an important measure of the ERAS model. Relevant guidelines also recommend that patients can move in bed after waking up from surgery, and it is advisable to get out of bed as soon as possible 24 hours after surgery. Early postoperative ambulation is beneficial to promote the recovery of intestinal peristalsis in patients, thereby accelerating gas and defecation, and implementing enteral nutrition as soon as possible. It is of great significance for preventing complications such as deep vein thrombosis, lung infection, and skin pressure injury, shortening hospital stay and reducing hospitalization costs.

[0004] At present, medical institutions mainly use the central negative pressure device on the wall to provide negative pressure suction function, and the drainage tube needs to be continuously negatively suctioned. Due to the limitations of these equipment and facilities, patients can only rest in bed or do some bed exercises. At present, there is no negative pressure drainage equipment on the market that is easy to move, which cannot provide the necessary support for patients to get out of bed and move around, which is not conducive to rapid recovery after surgery. Summary of the invention

[0005] The purpose of the present invention is to provide a portable mobile device with negative pressure drainage that is beneficial to postoperative recovery, which is convenient for carrying the negative pressure suction device for movement, so as to solve the defects mentioned in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0010] As a further improvement, an installation cavity is provided in the support plate, and a movable block is slidably installed in the installation cavity along the length direction of the installation shaft. A spring is provided in the installation cavity for pushing one side of the movable block to extend out of the support plate; a boss is provided on the movable block, and when the slider slides to the first end or the second end, the boss respectively abuts against the opposite sides of the outer wall of the installation shaft and limits the slider from sliding along the slide groove.

[0011] As a further improvement, a groove is provided on the front side of one end of the mounting shaft close to the support plate, a guide slope is provided in the groove, one end of the guide slope is connected to one end of the mounting shaft close to the support plate; when the movable block slides from the first end to the second end from front to back, the boss is guided by the guide slope and causes the movable block to be retracted inward into the mounting cavity.

[0012] As a further improvement, a connecting column is vertically fixedly installed on the bottom of the tray, and a positioning hole is provided on the pallet for the connecting column to be inserted, and the positioning hole is connected to the mounting cavity; a movable plate is installed in the mounting cavity for radial sliding along the positioning hole, and the sliding direction of the movable plate is perpendicular to the sliding direction of the movable block, a locking tongue is fixedly installed on the movable plate, and a locking groove is provided on the connecting column for the locking tongue to be inserted; a sliding pin is fixedly installed on the movable block, and a guide groove matching the sliding pin is provided on the movable plate, and when the movable block moves, the sliding pin acts on the guide groove and drives the movable plate to move.

[0013] As a further improvement, the guide groove includes a linear groove extending along the sliding direction of the movable block, one end of the linear groove is connected to a bevel groove, when the movable block or the boss abuts against the end of the mounting shaft, the sliding pin moves into the linear groove and the lock tongue is inserted into the lock groove; when the movable block and the boss are separated from the end of the mounting shaft, the sliding pin moves to the end of the bevel groove away from the linear groove and the lock tongue is separated from the lock groove.

[0015] As a further improvement, the supporting component is a supporting wheel rotatably mounted on the walking aid, and the axis of rotation of the supporting wheel extends laterally.

[0016] As a further improvement, an infusion stand cannula is fixedly mounted on the walker.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The support plate is rotated forward to a horizontal state and unfolded, so that the supporting component at the front side supports the seating surface of the support plate, so that the tray and the negative pressure suction device can be installed on the support plate, and negative pressure drainage can be continuously performed while the patient pushes the walker. It is convenient to use and is conducive to the rapid recovery of the patient after surgery;

[0019] The support plate is rotated backward to a horizontal state and unfolded, so that the supporting parts at the rear side support the instrument placement surface of the support plate, so that the patient can sit on the cushion to rest after being tired from activities, and the functions are more complete;

[0020] When the tray and the negative pressure suction device are installed on the support plate, the support plate can be pushed to move backward, so that the rear end of the support plate moves to the top of the supporting component located at the rear side, and the supporting components on the front and rear sides respectively support the bottom of the support plate on the front and rear sides of the sliding bracket, thereby limiting the angle of the support plate, preventing the support plate from swinging up and down when the walker encounters bumps, and improving the stability of the placement of the negative pressure suction device;

[0021] When the slider slides to the second end of the slide slot to lock the angle of the support plate, the boss abuts against the side of the outer wall of the mounting shaft away from the second end, so that the support plate and the sliding bracket cannot slide relative to each other, thereby preventing the support plate from accidentally sliding forward and separating from the supporting component at the rear side, and achieving higher reliability;

[0022] When the slider slides to the second end of the slide slot to lock the angle of the support plate, the movable block extends out of the mounting cavity and abuts against the end of the mounting shaft. The movable block drives the movable plate to move through the sliding pin and inserts the locking tongue into the locking slot, thereby limiting the connection column from being pulled out of the positioning hole, thereby preventing the tray and the negative pressure suction device from accidentally slipping off when the patient pushes the walker.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 15 As shown, a portable mobile device with negative pressure drainage that is beneficial to postoperative rehabilitation includes a walker 1 for hand-holding and pushing, which is used to assist patients to get out of bed and improve the safety of patients to get out of bed. In this embodiment, the direction in which the patient pushes the walker 1 is the front end of the walker 1. The walker 1 includes two inverted U-shaped handrails 2 that are relatively arranged on the left and right. The handrails 2 are specifically provided with a handrail portion extending forward and backward at the top, and the front and rear ends of the handrail portion are respectively integrally formed with vertical arms extending downward. An upper crossbar 3 and a lower crossbar 4 that are relatively arranged up and down are fixed or welded between the vertical arms on the front sides of the two handrails 2 by bolts. The lower ends of the two vertical arms of the handrails 2 are respectively installed with moving wheels, and the two moving wheels located at the rear are universal wheels with brakes, which are convenient for braking the walker 1.

[0042] The front end of the walker 1 is rotatably mounted with a sliding bracket 5 located between the upper crossbar 3 and the lower crossbar 4. The axis of rotation of the sliding bracket 5 extends laterally. The two handrails 2 are respectively fixed with laterally extending mounting shafts 6 by bolts or welded thereto. The left and right ends of the sliding bracket 5 are rotatably connected to the corresponding mounting shafts 6 by bearings. A support plate 7 is slidably mounted on the sliding bracket 5 along the radial direction of the mounting shaft 6. The plane where the support plate 7 is located is parallel to its sliding direction. A cushion 8 is provided on one side of the support plate 7. A tray 9 is detachably mounted on the other side of the support plate 7. A negative pressure aspirator 10 is detachably mounted on the tray 9. The negative pressure aspirator 10 has a built-in power supply. In the initial state, as Figure 1 and Figure 2 As shown, the support plate 7 is in a vertically upward retracted state, and the front and rear sides of the support plate 7 are respectively a seating surface 11 and an instrument placement surface 12, the seating surface 11 is provided with a cushion 8, and the instrument placement surface 12 is not installed with a tray 9 at this time, and the sliding bracket 5 is sleeved on the outer side of the lower end of the support plate 7 in a C-shape, as shown in FIG. Figure 6 As shown, the sliding bracket 5 is provided with an opening on one side corresponding to the instrument placement surface 12 . Or the corresponding limit lever 13 is rotated and adjusted to make its lower end deviate from the upper end of the support plate 7 so as to rotate and unfold the support plate 7 forward or backward to realize different functions of the support plate 7.

[0043] Supporting components 14 for supporting the support plate 7 are respectively installed on the handrails 2 located at the front and rear sides of the sliding bracket 5. When any supporting component 14 supports the support plate 7, the support plate 7 is in a horizontal state.

[0044] Specifically, the support plate 7 is rotated forward to a horizontal state and unfolded, so that the supporting member 14 located at the front side supports the seating surface 11 of the support plate 7, as shown in FIG. Figure 4 As shown, the instrument placement surface 12 of the support plate 7 is rotated to an upward state, so that the tray 9 and the negative pressure suction device 10 can be installed on the instrument placement surface 12 of the support plate 7. When the patient pushes the walker 1, the negative pressure suction device 10 provides continuous negative pressure drainage for the patient. In this embodiment, the rear end of the tray 9 is provided with a placement slot 15 for placing a drainage bottle or other sundries, such as Figure 5As shown, a vertically extending T-shaped slider 16 is fixedly installed on the rear side of the negative pressure suction device 10 by screws, and a slot 17 matching the T-shaped slider 16 is installed on the front side of the placement slot 15 by bolts, thereby improving the installation stability of the negative pressure suction device 10.

[0045] Alternatively, the support plate 7 is rotated backward to a horizontal state, so that the supporting member 14 at the rear side supports the instrument placement surface 12 of the support plate, and the seating surface 11 of the support plate 7 is rotated to an upward state, such as Figure 3 As shown, the patient can sit on the cushion 8 to rest after being tired from the activity.

[0046] The seating surface 11 and the instrument placement surface 12 of the support plate 7 are both provided with a slide groove 18 extending in a radial direction parallel to the installation axis 6. Figure 7 As shown, a slider 19 matching the slide groove 18 is provided on the inner wall of the sliding bracket 5, which limits the sliding stroke of the support plate 7. The two ends of the slide groove 18 along the length direction are respectively a first end 20 and a second end 21. When the slider 19 slides to the first end 20, the support plate 7 is rotated so that the supporting component 14 on the front or rear side supports the support plate 7; when the supporting component 14 on the front side supports the support plate 7, the slider 19 is slid to the second end 21 so that the supporting components 14 on both the front and rear sides support the support plate 7.

[0047] In the initial state, the support plate 7 remains in a state of extending vertically upwards. Figure 7 As shown, the slider 19 is located at the first end of the slide slot 18, and the sliding bracket 5 is located at the lower end of the support plate 7; when the patient needs to use the rest function of the support plate 7, the support plate 7 can be rotated backward to a horizontal state, so that the supporting component 14 located at the rear side supports the instrument placement surface 12 of the support plate; in addition, as shown Figure 2 As shown, a reinforcing rod is welded between the two vertical arms of the handrail 2, and an auxiliary plate 22 for supporting one end of the pallet 7 away from the sliding bracket 5 is fixedly installed on the inner side of the reinforcing rod by bolts. When the seating surface 11 of the pallet 7 faces upward, the bottom of the pallet 7 is supported at the same time by the supporting component 14 located on the rear side and the auxiliary plate 22, thereby enhancing the load-bearing capacity of the pallet 7.

[0048] Alternatively, when the patient needs to use the negative pressure aspirator 10 to aspirate the effusion while moving, the support plate 7 can be rotated forward to a horizontal state so that the supporting member 14 at the front side supports the seating surface 11 of the support plate. Figure 4 As shown, the tray 9 and the negative pressure aspirator 10 are then mounted on the instrument placement surface 12 of the support plate 7, and then the support plate 7 is pushed backward to slide the slider 19 to the second end 21 of the slide groove 18, as shown in FIG. Fig.11 and Fig.12As shown, at the same time, the rear end of the support plate 7 moves to the top of the supporting component 14 located on the rear side, and the supporting components 14 on the front and rear sides respectively support the bottom of the support plate 7 on the front and rear sides of the sliding bracket 5, thereby limiting the angle of the support plate 7, preventing the support plate 7 from swinging up and down when the walker 1 encounters bumps during movement, and improving the stability of the negative pressure suction device 10.

[0049] like Fig.10 and Fig.14 As shown, a mounting cavity 23 is provided in the support plate 7, and a movable block 24 is slidably installed in the mounting cavity 23 along the length direction of the mounting shaft 6. Two movable blocks 24 are arranged opposite to each other on the left and right sides, and strip holes 25 for the corresponding movable blocks 24 to pass through are respectively provided on the left and right side walls of the mounting cavity 23. The movable block 24 is provided with an ear plate 26 located in the mounting cavity 23 to prevent the movable block 24 from falling off from the mounting cavity 23. Slide rods 27 extending left and right along the length direction of the mounting shaft 6 are respectively fixedly installed on the left and right side walls of the mounting cavity 23. The ear plates 26 on the movable block 24 are slidably installed on the corresponding slide rods 27. A stopper 28 is provided at one end of the slide rod 27 away from the side wall of the mounting cavity 23, and a spring 29 is sleeved on the slide rod 27 located between the stopper 28 and the ear plate 26. When there is no external force, the thrust of the spring 29 acts on the ear plate 26 and causes one side of the movable block 24 to extend out of the outside of the support plate 7. The part of the movable block 24 extending out of the outside of the support plate 7 is in the shape of a long strip extending along the length direction of the slide groove 18. The end of the mounting shaft 6 away from the handrail 2 extends into the interior of the sliding bracket 5. At this time, the projection of the side of the movable block 24 extending out of the support plate 7 along the length direction of the slide groove 18 is located on the outer peripheral wall of the corresponding mounting shaft 6.

[0050] A boss 45 is integrally formed on one side of the movable block 24 opposite to the end of the mounting shaft 6. The boss 45 is in the shape of a long strip extending along the length direction of the slide slot 18. Figure 8 and Fig.12 As shown, when the slider 19 slides to the first end or the second end of the slide slot 18 , the bosses 45 respectively abut against opposite sides of the outer wall of the mounting shaft 6 and restrict the slider 19 from sliding along the slide slot 18 .

[0051] In the initial state, if Figure 8 As shown, the slider 19 is located in the first end 20 of the slide groove 18, the boss 45 and the movable block 24 do not contact the end of the mounting shaft 6, the spring 29 can push the movable block 24 to pop out completely, and make one end of the boss 45 abut against the side of the outer wall of the mounting shaft 6 away from the first end 20, thereby limiting the slider 19 from sliding toward the second end 21 of the slide groove 18, and at the same time preventing the support plate 7 and the sliding bracket 5 from sliding relative to each other, so as to keep the support plate 7 stable when the support plate 7 is folded upward or the patient sits on the cushion 8.

[0052] Or when the support plate 7 is rotated forward to a horizontal state, the elastic force of the spring 29 is overcome and the movable block 24 and the boss 45 are pressed inward, so that the movable block 24 and the boss 45 are retracted into the installation cavity 23, so as to push the support plate 7 to move backward, and the slider 19 slides the second end 21 of the slide groove 18 to lock the angle of the support plate 7; when the slider 19 slides to the second end 21 of the slide groove 18, the boss 45 completely passes the installation shaft 6 backward, the movable block 24 and the boss 45 are released, and the spring 29 pushes the movable block 24 to partially pop out, and at the same time, the other end of the boss 45 abuts against the side of the outer wall of the installation shaft 6 away from the second end 21, as shown in FIG. Fig.12 As shown, the support plate 7 and the sliding bracket 5 cannot slide relative to each other, so as to prevent the support plate 7 from accidentally sliding forward and separating from the supporting component 14 at the rear side.

[0053] like Figure 8 and Fig.15 As shown, a groove 30 is provided on the front side of one end of the mounting shaft 6 close to the support plate 7, and a guide slope 46 is provided in the groove 30, and one end of the guide slope 46 is connected to the end of the mounting shaft 6 close to the support plate 7; Fig. 9 As shown in the figure, when the support plate 7 rotates forward to a horizontal state and the movable block 24 is fully ejected, the projection of the boss 45 and the side of the movable block 24 extending out of the support plate 7 along the length direction of the slide groove 18 completely falls on the guide slope 46. When the movable block 24 slides from the first end 20 to the second end 21 from front to back, the boss 45 is guided by the guide slope 46 and causes the movable block 24 to be retracted inward into the installation cavity 23.

[0054] Specifically, after the support plate 7 is rotated forward to a horizontal state, the support plate 7 is directly pushed to move backward. When the support plate 7 drives the boss 45 to contact the guide slope 46 backward, the boss 45 and the movable block 24 are guided by the guide slope 46 to move inward and retract into the installation cavity 23, so that the slider 19 can slide from the first end 20 of the slide groove 18 to the second end 21 without manually pressing the movable block 24 inward, thereby locking the angle of the support plate 7 more conveniently.

[0055] like Figure 4 and Figure 5 As shown, a connecting column 31 is vertically fixedly installed at the bottom of the tray 9, and four connecting columns 31 are distributed in a rectangular array. A supporting foot 32 is also fixedly installed at the bottom of the tray 9, and the bottom of the supporting foot 32 is flush with the lower end of the connecting column 31. When the tray 9 is placed on the desktop, the connecting column 31 and the supporting foot 32 can provide a stable support effect; the instrument placement surface 12 of the tray 7 is provided with a positioning hole 33 for the connecting column 31 to be inserted, and the instrument placement surface 12 of the tray 7 is also provided with a positioning groove 34 matching the supporting foot 32. The positioning hole 33 is connected to the installation cavity 23, as shown in FIG. Fig.10 and Fig.14As shown, a movable plate 35 is installed in the installation cavity 23 along the radial sliding direction of the positioning hole 33, and the sliding direction of the movable plate 35 is perpendicular to the sliding direction of the movable block 24. In this embodiment, a sliding column 36 is fixedly installed on one side wall of the installation cavity 23, and a waist hole 37 matching the sliding column 36 is provided on the movable plate 35 to guide the sliding of the movable plate 35. A stopper is provided at one end of the sliding column 36 away from the side wall of the installation cavity 23, so that the movable plate 35 is tightly attached to one side wall of the installation cavity 23; two movable plates 35 are relatively provided, and the two movable plates 35 correspond to the two rows of connecting columns 31 respectively, and the movable plate 35 is fixed by screws. It is equipped with locking tongues 38 corresponding to the two connecting columns 31 in a corresponding row, and the corresponding connecting columns 31 are provided with locking grooves 39 for the locking tongues 38 to be inserted; one end of the movable block 24 located in the installation cavity 23 is fixedly installed with a sliding pin 40 corresponding to the movable plate 35, the sliding column 36 and the sliding pin 40 are both parallel to the axial direction of the positioning hole 33, and the end of the movable block 24 located in the installation cavity 23 is staggered with the movable plate 35 along the length direction of the sliding pin 40, and the movable plate 35 is provided with a guide groove 41 matching the sliding pin 40. When the movable block 24 moves, the sliding pin 40 acts on the guide groove 41 and drives the two movable plates 35 to move.

[0056] Specifically, if Fig.14 As shown, the guide groove 41 includes a linear groove 42 extending along the sliding direction of the movable block 24, and the linear groove 42 is connected to an end thereof close to the corresponding movable block 24 with an oblique groove 43, and the oblique groove 43 is inclined relative to the linear groove 42. When the movable block 24 or the boss 45 abuts against the end of the mounting shaft 6, the sliding pin 40 moves into the linear groove 42 and inserts the locking tongue 38 into the corresponding locking groove 39; when the movable block 24 and the boss 45 are separated from the end of the mounting shaft 6, the sliding pin 40 moves to the end of the oblique groove 43 away from the linear groove 42 and separates the locking tongue 38 from the locking groove 39.

[0057] When the slider 19 slides to the first end 20 of the slide slot 18, as shown in FIG. Fig. 9 and Fig.10 As shown, the movable block 24 and the boss 45 are both offset from the end of the mounting shaft 6, and the spring 29 can push the movable block 24 to pop out completely; when the slider 19 slides to the second end 21, as shown in FIG. Fig.12 and Fig.13 As shown, the movable block 24 is facing the end of the mounting shaft 6, and at this time the spring 29 can only push the movable block 24 to partially pop out.

[0058] In the initial state, if Figure 8As shown, the slider 19 is located in the first end 20 of the slide groove 18, the boss 45 and the movable block 24 do not contact the end of the mounting shaft 6, the spring 29 can push the movable block 24 to pop out completely, and the movable block 24 drives the sliding pin 40 to move to the end of the inclined groove 43 away from the linear groove 42, at this time, the connecting column 31 at the bottom of the tray 9 can be smoothly inserted into the corresponding positioning hole 33; after the support plate 7 is rotated forward to a horizontal state, as shown in FIG. Figure 4 , Fig. 9 and Fig.10 As shown, first, the tray 9 and the negative pressure aspirator 10 are installed on the instrument placement surface 12 of the tray 7, and the connecting column 31 at the bottom of the tray 9 is inserted into the corresponding positioning hole 33, and then the tray 7 is pushed to move backward, so that the slider 19 slides from the first end 20 of the slide groove 18 to the second end 21. When the boss 45 completely passes through the installation shaft 6 backward, as shown in FIG. Fig.12 and Fig.13 As shown, the spring 29 pushes the movable block 24 to partially pop out, so that the movable block 24 extends out of the mounting cavity 23 and abuts against the end of the mounting shaft 6. During this process, the sliding pin 40 is driven by the movable block 24 to move to the straight groove 42 through the inclined groove 43. The sliding pin 40 acts on the guide groove 41 and drives the two movable plates 35 to approach each other. The two movable plates 35 respectively drive the locking tongues 38 to insert into the corresponding locking grooves 39, thereby limiting the connection column 31 from being pulled out from the positioning hole 33, fixing the tray 9 to the instrument placement surface 12 of the support plate 7, and preventing the tray 9 and the negative pressure aspirator 10 from accidentally slipping when the patient pushes the walker 1.

[0059] In this embodiment, the supporting component 14 is a supporting wheel, and supports are respectively fixedly installed on the handrails 2 located on the front and rear sides of the sliding bracket 5 by bolts. A supporting wheel is rotatably installed on each support, and the axis of rotation of the supporting wheel extends laterally. When the support plate 7 is rotated forward to a horizontal state, the supporting wheel can reduce the resistance that pushes the support plate 7 to move backward.

[0060] An infusion stand cannula 44 is welded on the hand support 2, which is convenient for inserting the infusion stand and has more complete functions.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
